Methods of Communication

Core Concept

Communication is the transmission of information, ideas, emotions, and thoughts between individuals through speech, signals, writing, or behavior.

• Verbal Communication
Use of sounds and words to express thoughts. Divided into Oral/Spoken (face-to-face, phone, presentation) and Written (emails, letters, reports, memos).
• Non-Verbal Communication
Exchange of information without words using body language, facial expressions, eye contact (oculesics), gestures, posture, touch (haptics), and personal space (proxemics).
• Visual Communication
Conveying ideas and information through visual aids such as signs, symbols, diagrams, infographics, graphs, and traffic lights.

Communication Cycle & Importance of Feedback

Exam Essential

The communication cycle is a two-way process that is incomplete without feedback.

• Communication Process Steps
1. Sender conceives idea; 2. Sender encodes message; 3. Message transmitted through Channel; 4. Receiver decodes message; 5. Receiver sends Feedback.
• Importance of Feedback
Ensures the message was received and accurately interpreted. Types: Specific feedback (actionable guidance) vs Non-specific feedback (general reaction).

Barriers to Effective Communication

CBSE High Yield

Any factor that distorts or prevents the accurate reception and understanding of a message.

• Physical Barriers
Environmental distance, background noise, poor lighting, faulty communication equipment, or physical obstacles.
• Linguistic & Semantic Barriers
Use of complex technical jargon, dialect differences, ambiguous words, or language unfamiliarity.
• Organizational & Cultural Barriers
Rigid organizational hierarchies, differing cultural norms, and status consciousness.
• Psychological & Emotional Barriers
Prejudices, personal biases, stress, anxiety, anger, and lack of active listening.
